BALANCED GOVERNOR-VALVE.

SPECIFICATION forming part of Letters Patent No. 448,107, dated December 23, 1890.

Application filed August 22, 1890. Serial No, 362,728. (No model.)

To all whom it may concern.-

Be it known that I, FRED G. OLIN, of Buffalo, in the county of Erie and State of New York, have invented certain new and useful Improvements in Balanced Governor-Valves; and I do hereby declare that the following description of my said invention, taken in connection with the accompanying sheets of drawings, forms a full, clear, and exact specification,which will enable others skilled in the art to which it appertains to make and use the same. 7

This invention has general reference to improvements 011 a balanced valve; and it consists, essentially, in the novel and peculiar combination of parts and details of construction, as hereinafter first fully set forth and described, and then pointed outin the claims.

In the drawings already mentioned, which serve to illustrate my said invention more fully, Figure 1 is a side elevation of my improved balanced valve. Fig. 2 is alongitudinal sectional elevation of the same. Fig. 3 is Fig. 4: is a sectional plan in line m a: of Fig. 2. Fig. 5 is an elevation of the valve detached.

Like parts are designated by corresponding letters of reference in all the figures.

The object of this invention is the production of an efficient and simple balanced valve.

for steam and Water pipes, air-pipes, and also for governors and similar uses.

To attain this result I construct this valve of a metallic body A, having the usual internally-screw-threaded branches B B for the reception of the pipes O C. \Vithin this body is a central chamber D, connecting with the branch B, and an annular chamber D, connecting with the branch B and with the central chamber D through two diametrically-opposite passages cl (1 in the bottom D of said central chamber, and by two similar passages o a in a removable seat, hereinafter to be referred to, all as clearly shown in Fig. 1. Upon the top surface of this body A there is an extern ally-screw-threaded annulus E, upon which is screwed an open cap F, as shown in Figs. 1, 2, and 3, said cap being adapted to hold in position the balanced valve, consisting of a valve-spindle G, carrying on its upper end a handle H and terminating in fanshaped wings G on its lower end, which wings bear upon the upper surface of the bot tom D within the chamber D. At asuitable distance above these wings are located further fan-shaped Wings G ,which bear against the under surface of a disk J, formed in one piece with a cylinder J, located a suitable distance above said disk J, so as to afford a channel j, Figs. 2 and 5, there being in the disk J fan-shaped openings a a, corresponding to the similar openings d d in the bottom D, said cylindrical portion J fitting the opening E in the top of the body A a nice fit, while the cap F holds the same down, so that the lower edge of the disk J bears upon the upper edge of the annulus A, by which the chamber D is formed, and makes a tight joint at their junction. An elastic or slightly-elastic washer is is placed between the cap F and the cylinder J to make a tight joint at the upper end of said cylinder and the body A. It will now be observed that the spaces 9 g between the fan-shaped wings G, and also the spaces g bet-ween the wings G, form passages, through which the steam or other fluid, in connection with which the valve may be used, may enter and escape in a manner hereinafter to be described.

In the center of the lower end of the valvestem G there is formed arecess c, of suitable diameter, while in the bottom D there is located a minute passage b,by which the valve is forced slightly upward, as will farther on appear.

In operation steam or other fluid is assumed to enter through the branch B into the annular chamber D, from whence it will pass through the fan-shaped openings (1 a and d cl and the spaces g g in the valve, and thence pass from the central ohamberD through the.

branch B. In this case it is further assumed that the handle H is so placed, preferably with the run of the pipes, that the passages g g register with those marked cl (6' and on; but if the handle ll be moved one-fourth of a turn in either direction, so as to revolve the valve correspondingly, then the passages g 9 would not be opposite (1 ct and a a, and there by communication between the branch B and the chamber D intercepted, and the wings,being opposite the respective apertures, would close the valve. It will be further observed that the fluid under pressure passes through the top and bottom spaces of the valve simultaneously, so that there is no pressure upon the valve-1 (a, it being in balance, except as to the recess 0 in the bottom of the valve-stem, the diameter of which nearly equals that of said valve-stem, and into which the fluid under pressure may enter through the central orifice b in the bottom I)", which is in communication with the pressure side of the valve. On account of theintroduction of this recess there is a slight upward pressure on the said valve, tending to keep the wings G against the said seat of the disk .I, which I prefer to preventleakage past the valve-stem G in the cylinder J. It is obvious, however, that the fluid under pressure may enter the branch Band escapefromthc branch I; without seriously affecting the operation of the valve.

The balanced valve heretofore described is especially adapted for use as a regulatingvalve, a governor-valve, and in all situations where a perfectlybalanced valve is a desideratum. It may be readily produced by the ordinary tools and machines in brass-goodsmanufacturing establishments, and it will not cost any more than any otherfirst-class valve.

One of the advantages of the construction of this valve is the readiness with which repairs in case of leakage of the valve-seats may be made by simply lowering the upper edge of the annulus A, to lower the cylinder J accordingly, and by screwing up the cap F.

Having thus fully described my invention I claim as new and desire to secure to me by a Patent of the United States- 1. The balanced valve hereinbeforc described, consisting, essentially, of the body A, having branches B B, and annulus A, provided with the bottom D, having passages (Z cl, the valve consisting of the stem G, having fan-shaped wings on its lower end and similar wings G above the same, the removable valve-seat consisting of the cylinder J, having the disk J, provided with the passages to a, the cap E, and the handle II, as and for the object stated.

2. In a balanced valve, the combination, with a fixed seat, of a removable seat consisting of a disk having fan-shaped passages ad, cylinder J, located above said disk and affording the channelj, said seats being adapted to engage a suitable valve, as and for the purpose set forth.

3. In a balanced valve. the combination of a suitable casing having a valve, as described, provided with a recess in its under side, and the passage 1) in the seat, whereby said valve is forced upward, as and for the purpose set forth.

In testimony that I claim the foregoing as my invention I have hereto set my hand in the presence of two subscribing witnesses.
